| Name | Color | State | Description |
|---|---|---|---|
| SYS | Blue | Off | The reader is power off. |
| On | The reader is powered on and working properly. | ||
| 20Hz flashing | Tags was detected in the main identification area (RSSI signal is the strongest). | ||
| 8Hz flashing | Tags was detected in the secondary identification area (RSSI signal is medium). | ||
| 4Hz flashing | Tags was detected in the critical identification area (RSSI signal is weak). |
The tag should be in the center area of the sensing range:
The KRH-M30G can be flush-mounted in metal. Allow for a possible reduction in the field data. To avoid any influence on the field data, the distance "R" should be kept to ≥40mm.
In order to avoid potential conducted interference, it is recommended to use nonmetallic brackets to cut off the transmission path of conducted interference.
KRH-M30G side by side: to avoid any influence between the readers, the distance "D" should be kept to ≥80mm.
KRH-M30G face-of-face: to avoid any influence between the readers, the distance "D" should be kept to ≥150mm.
